Children’s hiccuping may be caused by eating too much, too fast, inhaling cold air, food irritating the throat, or indigestion. Persistent hiccuping should prompt a visit to the hospital for a thorough check-up. If the trachea is injured, a bronchoscopy may be necessary, or the child can try to take a deep breath and hold it, or use stomach-soothing and anti-retching traditional Chinese medicine for treatment.
